Select Color from the Adjustment menu and press ENTER. While looking at the color bar 
pattern through a blue filter, adjust the color saturation level until the outermost (gray and 
blue) color bars appear to be a single shade of blue: 
Tint: Tint or “hue” is essentially the ratio of red to green in the color portion of the image. 
When tint is decreased, the image appears redder; when it is increased the image 
appears greener. To set the tint, select Tint from the Adjustment menu and press ENTER. 
While looking at the color bar pattern through a blue filter, adjust the tint level until the cyan 
and magenta color bars (on either side of the green bar) appear to be a single shade of 
blue. 
Like the brightness and contrast controls, the color and tint controls 
are interactive. A change to one may require a subtle change to the 
other in order to achieve the optimum setting.

Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust 
sharpness, select Sharpness from the Adjustment menu and press ENTER. On your 
external test pattern source, select a pattern like the one shown in 
Figure 4-5. Adjust as 
needed, looking for white edges around the transitions from black to gray and 
differently-sized lines in the “sweep” patterns at the top and bottom. Lower the sharpness 
setting to eliminate them. 
Figure 4-5. Typical Test Pattern for Adjusting Sharpness
Filter: The Filter setting controls the behavior of the Sharpness control. The available 
settings depend on the vertical resolution of the input signal, as follows: 
With a 480i signal, you can apply the sharpness control to either the input signal (1), 
the output signal (2), both (3) or neither (0). 
With a 480p or higher-resolution signal, the sharpness control is applied only to the 
output signal and only when you set the Sharpness Filter to “on” (1). 
The Sharpness setting has no effect if the Sharpness Filter (see 
below) is set to 0. Note

Sleep Timer: The Sleep Timer automatically puts the projector into standby mode after 
the amount of time you specify here. (A warning appears on-screen one minute before this 
is to occur.) 
Use the  or  button to set the timer for anywhere from 10 minutes to 3 hours, in 
10-minute increments. To disable the Sleep Timer, set it to 0. 
Lamp Hours: To find out how long the projector lamp has been in use, select Lamp 
Hours and press ENTER. 
OSD Timer: Use the  or  button to set the OSD Timer. This timer controls how long 
the menus remain on-screen after selecting them. Select from 0 to 60 seconds, in 
3-second increments. When you set the OSD to 0, the menus remain on-screen until you 
hide them by pressing MENU. 
To adjust the horizontal and vertical position of the OSD, select OSD Position and press 
ENTER. Then, press the 
 or  button to select Horizontal or Vertical and use the 
 or  button to adjust.

Freq. Adjusts the frequency of the signal.
Phase: Adjust the phase if the image (usually from an RGB source) shows shimmer or 
“noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the 
incoming signal. The effect of this control is similar to that of a tracking control on a 
VCR. 
For best results, use a good test pattern such as a smooth gray consisting of a clear 
pattern of black and white pixels, or a similar “half on, half off” graphic image. (You may 
find that you can stabilize the image at more than one point. Use either setting in this 
case.)

DNR: Use the  or  button to adjust the Digital Noise Reduction (DNR). DNR is useful 
for clearing up noisy images from interlaced SD sources. Adjust as desired, keeping in 
mind that reducing noise (which reduces high frequencies) may also soften the image. 
Set UpTo access advanced picture quality adjustments, use the up- or down-arrow keys to 
highlight Set Up and press ENTER. Use the number buttons on the remote to enter the 
Set Up menu passcode when prompted and press ENTER again. Then, press MENU on 
the remote control. 
White Balance: To remove any trace of color from the white areas of the projected 
image, choose White Balance from the Set Up menu and press ENTER. 
 Gamma: “Gamma” is a global setting that determines how gray shades are displayed 
between minimum input (black) and maximum input (white) for all signals. A good 
gamma setting helps to optimize blacks and whites while ensuring smooth transitions 
for the “in-between” values utilized in other grays. Unlike “Brightness” and “Contrast” 
controls, the overall tone of your images can be lightened or darkened without 
changing the extremes and all images will be more vibrant while still showing good 
detail in dark areas. 
In all but the most unusual situations, the appropriate “Gamma Selection” (see below) 
will produce accurate colors and a satisfying contrast level. However, it is sometimes 
necessary to adjust the red, blue and green gamma curves individually. To do this, 
select Gamma from the White Balance sub-menu and use the left- and right-arrow 
buttons to manipulate the on-screen slidebars. 
Gain: Use the Gain controls to correct color imbalances in the bright areas of the 
image. A good way to do this is to use a test pattern consisting mostly of solid white 
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, 
green or blue, decrease the Gain for that color.
Offset: Use the Offset controls in the White Balance sub-menu to correct color 
imbalances in the dark areas of the image. A good way to do this is to use a test 
pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the 
gray areas contain traces of red, green or blue, decrease the Offset for that color.
 Store Custom 1/Store Custom 2: When you are finished adjusting the Gamma, Gain 
and Offset, select Store Custom 1 or Store Custom 2 to store your settings. To recall 
them, set the Color Temperature to Custom 1 or Custom 2 in the Image Adjustment 
menu (refer to 
Picture Adjustment on page 46).

Gamma Selection: The normal gamma setting of 2.2 is correct for almost all signals and 
conditions. If excess ambient light washes out the image and it becomes difficult or 
impossible to see details in dark areas, lower the gamma setting to compensate. This will 
improve contrast while maintaining good details for blacks. Conversely, if the image is 
washed out and unnatural, with excessive detail in black areas, increase the setting. 
Again, good gamma improves contrast while maintaining good details for blacks and 
whites. 
SD Enhance: The SD Enhance menu gives you options for improving the quality of 
standard-definition, 480i images. (For 480p and higher-definition images, the controls in 
this menu are disabled.) Keep in mind that these controls add frequencies that are not 
present in the original signal, and may make images appear “noisy” if misused. 
 H Enhance/V Enhance: These controls can improve the apparent horizontal and/or 
vertical resolution of the image. 
 Chroma Enhance: This control adds chroma (color information) to the input signal 
and can make colors appear more vibrant and saturated. 
 H Threshold/V Threshold/Chroma Threshold: Set these to +11 or higher to 
activate the enhancement controls described above. Generally, the higher the 
threshold, the more noticeable the enhancements you make will be. 
RVR Adjust: Use the RVR Adjust control to increase or decrease the Reflectance Volume 
Regulation setting. RVR lets you control the aperture or iris size (the physical opening 
through the lens; similar to an “f-stop” on a camera). Doing so allows you to optimize 
brightness and contrast according to the amount of ambient light in the viewing area. 
Use a higher setting for rooms with lots of ambient light. Use a lower setting for more 
“theater-like” viewing conditions (little or no ambient light). 
 
HDTV Adjust: Use the controls in the HDTV Adj. sub-menu to improve the display of 
high-definition source material. These controls allow you to make adjustments 
independently for each HD signal type (as opposed to the per-input controls in the 
Picture 
Adjustment menu).

 Signal Fine Tune: This sub-menu displays current input signal timing information and 
provides the following advanced settings. 
Clamp Place: “Clamping” refers to the removal of any DC offset from the analog 
input signal so that it can be accurately digitized. Clamping normally occurs a short 
time after the trailing edge of the horizontal sync signal (H-sync), when the video 
source is known to be producing black. The analog-to-digital converter in the 
RS-1100 uses the input signal at this point as its black level reference and 
processes all other signal levels accordingly. 
 
 
Clamp Place is the number of pixel periods (1 to 255 inclusive) that should pass after 
the trailing edge of H-sync before clamping starts. If images from an HD source 
appear excessively dim, try adjusting the Clamp Place to correct this.
Clamp Duration: Clamp Duration is the number of pixel periods (1 to 255 inclusive) 
for which clamping is active. For best results, set the clamp duration to include the 
majority of the black reference signal time that follows the H-sync signal trailing 
edge. Increase the Clamp Duration if you see brightness changes at the top of the 
screen and/or slow recovery from large changes in the average picture level (APL), 
or brightness.
Pre-Coast/Post-Coast: With some HD sources, H-sync may become distorted or 
disappear altogether during the vertical sync (V-sync) pulse period. With composite 
sync or sync-on-green RGB signals, H-sync may contain equalization pulses or 
other distortions during V-sync. 
 
 
To maintain proper signal timing, such distortions should be ignored; otherwise, 
“tearing” of the image at the top of the display may result. The solution is to employ 
“coasting,” which allows the pixel clock to free-run at its then-current frequency. It 
can do so for several lines without significant frequency drift. 
 
 
Pre-Coast sets the number of H-sync periods that Coast becomes active prior to 
V-sync. Post-Coast sets the number of H-sync periods that Coast stays active 
following V-sync. Increase one or both settings to correct jitter or instability in the 
image. 
SOG (Sync-On-Green) Threshold: SOG Threshold adjusts the voltage level of the 
RS-1100 Sync-on-Green signal detection circuitry. Adjust the SOG Threshold if an 
image from a “sync on green” RGB source is unstable or won’t display at all. Higher 
settings lower the SOG detection threshold in 10-millivolt steps; lower settings raise 
the threshold. The range is from 0 (330 mV) to 31 (10 mV) inclusive. The default 
setting is 23 (100 mV) and should rarely require adjustment.
